It seems How did you do this, can this be done upfront or should this be done after the upgrade? ceph-kvstore-tool bluestore-kv /var/lib/ceph/osd/ceph-15 compact I tried getting the status, but it failed because the osd was running. Should I prepare for stopping/starting all the osd daemons to do this compacting? _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-le...@ceph.io
